unity中绑定动画的行为系统

主要代码逻辑是创建一个action队列,当动画播放结束时就移除队头,执行后面的事件

 
public class Enemy : MonoBehaviour
{
      
    
        public event Action E_AnimatorFin;//当动画播放完毕时
 
        public Action DefaultAction;//默认事件
     
        public Dictionarystring> EventAnimator= new();//Event对应的动画
        public List Eventlist=new();//要做的event列表
 
        private Animator ani;
        
        
        public virtual void Start()
        {
              
                ani = GetComponent();
                E_AnimatorFin += OnAnimatorFinish;
             
                StartCoroutine(SpawningAnimator());
                IEnumerator SpawningAnimator()
                {
                        yield return new WaitForSeconds(0.02f);
                        PlayAnimator(ani, EventAnimator[ Eventlist[0]],
                                () =>
                                {
                                        Debug.Log("动画播放前执行代码"+ EventAnimator[ Eventlist[0]]);
                                },
                                () =>
                                {
                                        E_AnimatorFin?.Invoke();
                                        Debug.Log("动画播放完执行代码");
                                });
                }
 
        }

        {
